Re: Romneya coulteri

It has become rather invasive in one of my garden beds;  (I am in Adelaide, South Australia.)  I cut it down by two-thirds after it has flowered.  However I suspect it is so rampant because it gets quite a bit of water from the drippers as the bed it's in has roses and fruit trees.

I have a steep rocky back yard.  I planted a Romneya in a pocket surrounded by huge boulders about 10 years ago.  I filled the pocket with all kinds of native soil, sand, perlite, and some bags of palm/cactus mix.  It has now filled the pocket and gets about eight feet tall each year.  In January I cut the plant back about 2-3 feet.  Years ago someone told me to cut it back to soil level.  I thought I almost killed it.  It set the plant back considerably.  I hardly ever give it supplemental water but if I did I think it would extend the blooming season.  I live in an eastern suburb of San Diego and we have this plant growing along the cliffs along the inland highways.  If you have the room and are aware of it's vigorous nature once establlished, it's a great garden plant.

Has anyone outside of Southern California grown Romneya coulteri sucessfully. More specifically I am wondering  if anyone is growing it in the Mediterranean basin or anywhere that has typical mediterranean alkaline soil.   I  would be interested to hear experiences. Its such a lovely plant.
